The point is you have a child who will soon look up to you and need you in her life every step of the way. That's the point. So no matter or what, even if it feels like there's nothing else, be your little princesses rock.
And don't just be a phone call on a birthday then eventually forget to do it after a couple of years like my Dad.
I am feeling the same way, the only difference is: I cause my own problems and I am the whats wrong with my life. its more difficult when its an internal conflict that you can never escape from. Hang in there Joe you will be just fine. Your a tough guy... well sorta ; )
